3. Stanley Knife – a sharp Stanley knife will be used to cut roofing felt before applying it.

4. Flat Pry Bar – a flat pry bar can also be used to remove old felt from a roof.

5. Brush (50mm) – a brush will be used to apply roofing felt adhesive. It makes sure that the glue is spread evenly and that excess pieces are removed from surfaces after they dry.

Steps for Properly Applying Roofing Felt Adhesive

Roofing felt adhesive should not be used on every surface that needs a roof. It’s important to use this product in specific areas where leaks are likely to occur.

If you need a permanent sealant, something like silicone caulk is recommended.

Roofing felt adhesive should be applied in the following order:

1. Clean the roof surface – before you begin to use the roofing felt adhesive, make sure that your surface is clean and free of dirt or other debris.

If you apply glue to a dirty area it will be no better than applying nothing at all.

2. Apply the felt adhesive on dry surface – roofing felt adhesive is best applied within 24 hours of installing the roofing felts themselves.

You should also wait until your area has had a chance to dry completely so that the glue will have the right conditions for drying properly too.

3. Place the felt – When the felt is at its optimal thickness, put it on the adhesive. Stick the felt to make sure it does not come off.

Rub and roll whenever needed to release any trapped air. The felt must be rolled up and a lightweight roller is used to spread the adhesive.

4. Join overlapping sections – The size of overlapping sections should be 75mm for the sides and 150mm at the end.

The felt adhesive is applied under the roofing felt and well compacted to make a solid connection on the sides.

5. Work on the timber structure – The initial layer of felt in a timber structure needs to be fastened down with nails. Then, for the following layers, more adhesive may be needed.

6. Prepare with primer the porous concrete surface – A primer is a necessary preparation for use. The adhesive will be more efficient. Make sure the primer is dry before putting any roofing felt on top.

7. Rest the felt – The felt needs to rest for at least 24 hours. After checking for full adhesive, check every side and end.

What Makes a Good Roofing Felt Adhesive?

Roofing felt melts at high temperatures, so it’s important that your roofing adhesive meets certain standards to ensure it has proper adhesion.

Roofing felt adhesive must be able to withstand heat, dampness, high roof traffic and remain flexible.

Roofers also need to know that once they have applied the adhesive everything will stay dry underneath the felts.

Pros for Using Roofing Felt Adhesive

Roofers are able to get a better hold with this type of glue than with nails or staples.

Rather than putting 200 nails in every square foot of roof, one adhesive holds the entire job together – saving you money on labor costs.

Cons for Using Roofing Felt Adhesive

Some adhesives can reduce the effectiveness of certain types of roofing felts. In order to be as efficient as possible, many types of felt require a product that is designed specifically for them.

If you choose a roof adhesive not made by the same manufacturer as your felt, it may not be able to stretch and contract with the roof properly.

The life of a roof felt depends on the strength of its installation. Properly installed roofing felt lasts around 10-20 years. The lifespan of a roof depends on how well it has been managed and maintained.
